From start to finish our experience with the owner Joana and Valentim, who met us, was wonderful. The flat was extremely clean and has all that you’d need for your stay. It’s on a pedestrianized street with lots of places to eat in short walking distances. FYI taxis are allowed on the street to drop people off but ours refused (and it was pouring rain outside). It made it a bit more difficult to find the flat but being in contact with Valentim via WhatsApp helped us.
My only negative is that the bed was really, really firm. That was uncomfortable for us but it would not stop us from staying here again though as there was so much to love about it.
If you get the chance eat at a lovely 5 table restaurant called “Metro & Meio” just up the hill. It was our favorite experience in Porto. His flaming Chorizo is a must! Also eat at Bom Sucesso Market where the food choices abound!
